Communication Device Role Determination for Seamless Network Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems like IEEE 802.11, the automatic setting of communication parameters is hindered when the roles of providing and receiving devices are not defined, leading to usability issues, especially when a new device joins an existing network.
Innovation Solution
A communication device and method that include a search unit to determine the role of another device as either a providing or receiving device based on information exchanged, allowing for seamless integration into established networks by adjusting roles dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic setting methods are used to easily set communication parameters, then ease of operation is improved, but device complexity increases due to role determination mechanisms
Solution Approach 1:
The communication device automatically determines its own role (providing device or receiving device) based on pre-stored second information and exchanged signals, without requiring user intervention. The device serves itself by making autonomous decisions about parameter provision based on its stored configuration information and the information received from other devices.
Solution Approach 2:
The device stores second information (indicating whether it can act as a providing device) in advance before the automatic setting process begins. This pre-stored information is used during the role determination phase to quickly and automatically decide the device's role, avoiding the need for complex real-time negotiations or user input.
2Adaptability or versatility
If roles of providing and receiving devices are not defined in advance, then adaptability is improved, but reliability deteriorates due to potential network disruption
Solution Approach 1:
The device's role is determined dynamically during the automatic setting process based on the combination of pre-stored second information and first information received from other devices. The device can adapt its role (providing or receiving) based on the current network situation and device capabilities, while still ensuring reliable network operation through this dynamic determination mechanism.
Solution Approach 2:
The role determination process uses feedback from exchanged signals (first information) between devices combined with pre-stored configuration data (second information) to make an informed decision. This feedback mechanism ensures that the role assignment is appropriate for the current network context, maintaining both adaptability and reliability.
3Adaptability or versatility
If a new device joins an established network, then adaptability is improved, but loss of information occurs when role assignment is incorrect
Solution Approach 1:
The device stores second information in advance that indicates its capability to act as a providing device. When a new device joins, this pre-stored information is immediately available for role determination, allowing the device to correctly assume the providing device role and share network parameters with the new device, preventing any loss of network information.

AI summary
When a communication device detects another communication device operating as a providing device that provides a communication parameter and when a communication parameter has already been set between the communication device and a different communication device or when the communication device is participating in the same network as that in which the different communication device is present, the communication device transmits a session overlap notice to the detected communication device.
